Bug Description

I just hit an issue with the following steps:

1. create vol
2. create backup (works fine uses incremental diff)
3. delete backup
4. create new backup (full copy forced because volume backup-snap exists and is not ignored)

The ceph backup driver needs to either (a) ignore the backup snap if the base it was applied to was deleted or (b) delete the backup snap when the backup is deleted if the base is being deleted.

    Fixed erroneous force full copy in ceph backup driver

    The following steps should not result in a forced full copy:

    1. create vol
    2. create backup (works fine i.e. uses incremental diff)
    3. delete backup
    4. create new backup (full copy forced because volume backup-snap exists and is not ignored)

    This patch resolves the above problem.
